Issue #1

Even though the knowledge base is enabled in the widget settings, it is not appearing on the start screen.

Issue #2

Even though it's installed properly, the chat widget is not showing up on the website.

Issue #3

Customers are complaining about the lack of real-time appearance of chat messages, often a page reload is required to see new messages.

Solution

1. Check the browser console for "Content Security Policy"-related errors like this:

sdk-code.js:2 Refused to connect to 'https://yourdomain.crunch.help/api/sdk/browser/knowledgebase' because it violates the following Content Security Policy directive: "connect-src 'self'

2. If you use the "Content Security Policy" header on your website, make sure to add HelpCrunch domains to the list of exceptions:

helpcrunch.com 
*.helpcrunch.com
wss://ws.helpcrunch.com
ucarecdn.com
*.crunch.help
